> This patch does not propose a simple API to reuse internal > debug hooks when replacing system (PyMem) allocators. Ok, this is now fixed with new patch (version 5). Nick does not want a new environment variable, so I added instead a new function PyMem_SetupDebugHooks() which reinstalls hooks to detect bugs if allocator functions were replaced with PyMem_SetAllocators() or PyObject_SetAllocators(). The function does nothing is Python is not compiled in debug more or if hooks are already installed (so the function can be called twice). I also added unit tests for PyMem_SetAllocators() and PyObject_SetAllocators()! And I added "versionadded:: 3.4" to the C API documentation.
